Which Type Of Pneumonia Is Contagious

Is There Any Way To Prevent Getting A Contagious Form Of Pneumonia

Pneumonia: types, causes, and treatment

Here’s where some vaccines come into playthere are actually a few different ones that can significantly lower your risk .

  • The flu vaccine: “The flu vaccine is actually very effective at preventing bacterial pneumonia, since influenza predisposes you to bacterial pneumonia as a secondary infection,” Dr. McGinniss says. He points out that it can also be helpful at preventing viral pneumonia from the influenza virus.
  • Pneumococcal vaccines: There are twovaccines available to prevent infections from the pneumococcus bacteria, the most common type of bacteria that causes pneumonia pneumococcal conjugate vaccine and the pneumococcal polysaccharide vaccine . These are usually recommended for adults over the age of 65 or older, people with chronic diseases, and people who smoke. “The current vaccines are very effective,” Dr. Panettieri says.
  • The Hib vaccine: Hib stands for Haemophilus influenzae type b, which is a type of bacteria that can cause pneumonia and meningitis. It’s recommended for all children under the age of five in the U.S., and is given to babies as young as two months old, the NHLBI says.
  • The COVID-19 vaccine: While the vaccines are new, they have been proven to lower your risk of contracting a severe form of the virus, which can include serious complications like pneumonia, Dr. McGinniss points out.

Aside from getting vaccinated, experts stress the importance of careful hand hygiene and doing your best to avoid people who are sick to lower your risk of pneumonia.

How To Avoid Catching Pneumonia

Some simple precautions and preventive measures can lower your risk of infection from a contagious form of pneumonia. Here are some pointers to protect yourself and your family:

  • Avoid smoking or being around anyone who is smoking to minimize exposure to toxins.12
  • If you are infected, always use a tissue to cover your nose and mouth while coughing or sneezing to prevent the germs from dispersing in the air or onto surfaces around you. Throw it out immediately after to avoid contaminating surfaces or passing on the germs.13
  • If anyone at home is infected, ensure their cutlery, glasses, and utensils are kept separate from everyone elses and washed separately to avoid contamination.14
  • If you or someone around you has pneumonia, be sure to wash your hands often.15
  • Lower the risk of catching infections by being vaccinated against them. Some of the infections you can be vaccinated against which could help you avoid catching pneumonia are flu, Hemophilus influenzae type b infection, measles, whooping cough, chicken pox, and pneumococcal disease.16
  • If you or someone around you has pneumonia, especially if symptoms are worsening, get treated right away. For bacterial infections, a simple course of oral antibiotics will do the trick, so dont put off getting medical attention.17 You might wind up infecting someone if you dont.


Pneumonia Kills More Children Than Any Other Infectious Disease

Many people associate pneumonia with the elderly, but it is actually the biggest infectious killer of children worldwide. It claims the lives of over 800,000 children under five every year, including over 153,000 newborns, who are particularly vulnerable to infection. That means a child dies from pneumonia every 39 seconds and almost all of these deaths are preventable.

What causes pneumonia?

Pneumonia is an acute respiratory infection of the lungs. It doesnt have one single cause it can develop from either bacteria, viruses or fungi in the air. When a child is infected, his lungs are filled with fluid and it becomes difficult to breathe. Children whose immune systems are immature or weakened such as by undernourishment, or diseases like HIV are more vulnerable to pneumonia.

What are the symptoms of pneumonia?

As pneumonia is an infection of the lungs, the most common symptoms are coughing, trouble breathing and fever. Children with pneumonia usually experience fast breathing, or their lower chest may draw in or retract when they inhale .

Is pneumonia contagious?

Pneumonia is contagious and can be spread through airborne particles . It can also be spread through other fluids, like blood during childbirth, or from contaminated surfaces.

Limit Contact With Others

One of the best things you can do when recovering from pneumonia is to limit your contact with others. As weve learned throughout the COVID-19 pandemicwhich can cause viral pneumoniastaying at least six feet away from others reduces the amount of viral or bacterial content they are exposed to as you breathe or talk.

When Can I Return To Work School And Regular Activities If I Have Pneumonia


You typically can resume your normal activities if your symptoms are gone, mild or improving and you do not have new or worsening:

  • Shortness of breath or tiredness
  • Chest pain
  • Mucus, fever or cough

If you are generally healthy, most people feel well enough to return to previous activities in about a week. However, it may take about a month to feel totally back to normal.

Can Pneumonia Be Prevented

Check with your healthcare provider about getting immunizations. The flu is a common cause of pneumonia. Because of that, getting a flu shot every year can help prevent both the flu and pneumonia.

There is also a pneumococcal vaccine. It will protect you from a common form of bacterial pneumonia. Children younger than age 5 and adults ages 65 and older should get this shot.

The pneumococcal shot is also recommended for all children and adults who are at increased risk of pneumococcal disease due to other health conditions.

Pneumonia Can Be Fatal

When you acquire pneumonia, it could affect only one lung, both lungs, or spread from one to the other. It causes the air sacs in your lungs, also called alveoli, to become inflamed. This is what makes it difficult to breathe. Doctors typically treat pneumonia with antibiotics, but it remains the leading cause of infectious disease death in children under age five across the world. As with the flu, pneumonia can also be deadly for elderly people.

Smokers and those with asthma have a greater likelihood of catching all different strains of the disease. However, bacterial infection is the most common cause among adults in the United States.

How Can I Help Myself Feel Better

If your doctor has prescribed medicine, follow the directions carefully.

You may feel better in a room with a humidifier, which increases the moisture in the air and soothes irritated lungs. Make sure you drink plenty of fluids, especially if you have a fever. If you have a fever and feel uncomfortable, ask the doctor whether you can take over-the-counter medicine such as acetaminophen or ibuprofen to bring it down. But don’t take any medicine without checking first with your doctor a cough suppressant, for example, may not allow your lungs to clear themselves of mucus.

And finally, be sure to rest. This is a good time to sleep, watch TV, read, and lay low. If you treat your body right, it will repair itself and you’ll be back to normal in no time.

How Does Pneumonia Spread

China admits Wuhan pneumonia virus contagious among people

The bacteria and viruses that cause pneumonia usually spread in tiny respiratory droplets when an infected person coughs or sneezes. If you are nearby, you can breathe in these droplets or they can land in your nose or mouth. Germs can also spread when you touch a surface that is contaminated with the infectious droplets, and then you touch your eyes, nose or mouth. Most of the time, your immune system stops these germs from infecting you. But sometimes they can enter your body and make you sick.

Note that some germs that cause pneumonia are not contagious. For instance, pneumonia caused by fungi is not spread from person to person.

Pleural Effusion Empyema And Abscess

In pneumonia, a collection of fluid may form in the space that surrounds the lung. Occasionally, microorganisms will infect this fluid, causing an empyema. To distinguish an empyema from the more common simple parapneumonic effusion, the fluid may be collected with a needle , and examined. If this shows evidence of empyema, complete drainage of the fluid is necessary, often requiring a drainage catheter. In severe cases of empyema, surgery may be needed. If the infected fluid is not drained, the infection may persist, because antibiotics do not penetrate well into the pleural cavity. If the fluid is sterile, it must be drained only if it is causing symptoms or remains unresolved.

In rare circumstances, bacteria in the lung will form a pocket of infected fluid called a lung abscess. Lung abscesses can usually be seen with a chest X-ray but frequently require a chest CT scan to confirm the diagnosis. Abscesses typically occur in aspiration pneumonia, and often contain several types of bacteria. Long-term antibiotics are usually adequate to treat a lung abscess, but sometimes the abscess must be drained by a surgeon or radiologist.

Respiratory And Circulatory Failure

Pneumonia can cause respiratory failure by triggering acute respiratory distress syndrome , which results from a combination of infection and inflammatory response. The lungs quickly fill with fluid and become stiff. This stiffness, combined with severe difficulties extracting oxygen due to the alveolar fluid, may require long periods of mechanical ventilation for survival. Other causes of circulatory failure are hypoxemia, inflammation, and increased coagulability.

is a potential complication of pneumonia but usually occurs in people with poor immunity or hyposplenism. The organisms most commonly involved are Streptococcus pneumoniae, Haemophilus influenzae, and Klebsiella pneumoniae. Other causes of the symptoms should be considered such as a myocardial infarction or a pulmonary embolism.

Is Walking Pneumonia Bacteria Or Virus

Pneumonia is an inflammation of the lung tissue caused by an infection. This may be a bacterial or viral infection. Walking pneumonia is a milder version of the disorder caused by Mycoplasma pneumoniae , and sometimes Chlamydia or Legionella . This is a bacterial infection that can affect children and adults.

What Are The Symptoms Of Pneumonia

Aspiration pneumonia: Treatment, complications, and outlook

The symptoms of bacterial pneumonia include:

  • Bluish color to lips and fingernails

  • Confused mental state or delirium, especially in older people

  • Cough that produces green, yellow, or bloody mucus

  • Fever

Mycoplasma pneumonia has somewhat different symptoms, which include a severe cough that may produce mucus.

Pneumonia Can Be Caused By Bacterial Viral Or Fungal Infections

Pneumonia is a type of lung infection that causes the air sacs in the lungs to fill with liquid.

There are different types of pneumonia. In most cases, pneumonia is caused by a bacterial or viral infection. In rarer cases, pneumonia can be caused by inhaling fluid into the lungs, or from a fungal infection.

However, healthcare providers arent always able to identify a cause for pneumonia: one study found that in up to 62% of pneumonia cases no pathogen like a virus, bacteria, or fungus is identified.

When people discuss types of pneumonia, they also consider how severe the infection is. For example, walking pneumonia is a nonmedical term thats used to refer to a mild case of pneumonia, where the patient can still be up and walking around. People also distinguish pneumonia cases by where they were picked up: for example, hospital-acquired pneumonia or community-acquired pneumonia.

More Severe Cases May Also Cause:

  • quick breathing
  • rapid heartbeat
  • nausea and vomiting

Some people get a sharp pain in their chest when they breathe in and out. This may be because the thin lining between the lung and ribcage, called the pleura, is infected and inflamed. This inflammation, called pleurisy, stops your lungs moving smoothly as you breathe.

The symptoms of pneumonia are often very similar to those of other chest infections, such as bronchitis, COPD flare-ups or bronchiectasis flare-ups. To get a proper diagnosis youll need to visit your GP.

If you feel unwell with these symptoms, see your GP or call 111. If you have chest pain, a rapid heartbeat, quick breathing, shivers or confusion, get urgent advice from your GP or call 999. Take extra care if youre over 65.

Is Pneumonia Contagious What To Know And How To Protect Yourself

by | Sep 22, 2021 | News

Though pneumonia is often thought of as a single illness, it actually comes in many different forms. While each type can cause the dangerous inflammation in your lungsthe result of an infection that leads to fluid or pus collecting in the lungsthe specific type of pneumonia can determine risk of severity, symptoms, and even treatment options.

Another thing that the specific type of pneumonia can shed light on: whether or not its contagious. . To get more information on those typesand what you need to know about how they present and how to avoid themwe tapped some infectious disease experts. Heres what you need to know about the contagious forms of pneumonia. To read the full story.

Who Is Most Likely To Get Pneumonia

China admits Wuhan pneumonia virus contagious among people

Although anyone at any age can contract pneumonia, there are certain groups that are at a higher risk than others. Individuals most likely to contract pneumonia include the elderly, children, people with chronic illnesses, and individuals with compromised or weakened immune systems.

Other risk factors that increase a persons risk of pneumonia include chronic lung diseases like COPD, smoking, brain disorders, immune system problems, serious illnesses like heart failure or diabetes, a recent surgery or trauma, and ongoing cancer treatment, or surgery for the nose, throat, mouth, or neck cancer.

Are There Treatments For Covid

Pneumonia may need treatment in a hospital with oxygen, a ventilator to help you breathe, and intravenous fluids to prevent dehydration.

Clinical trials are looking into whether some drugs and treatments used for other conditions might treat severe COVID-19 or related pneumonia, including dexamethasone, a corticosteroid.

The FDA has approved the antiviral remdesivir for treatment of patients hospitalized with COVID. The drug was origininally developed to treat the Ebola virus.

The agency rescinded an emergency use authorization for the anti-malarials chloroquine and hydroxychloroquine amid serious concerns about their safety and how well they worked against the virus.

How Long Are You Contagious With Walking Pneumonia After Antibiotics

Once a person who has pneumonia starts on antibiotics, he or she only remains contagious for the next 24 to 48 hours. This can be longer for certain types of organisms, including those that cause the disease tuberculosis. In that case, someone can remain contagious for up to two weeks after starting on antibiotics.

What Are The Main Differences Between Bacterial And Viral Pneumonia

Common symptoms of pneumonia include3

  • cough
  • difficulty breathing
  • increased breathing rate

When a patient presents with these symptoms, the next step is to examine the lungs with a stethoscope. With pneumonia, decreased breath sounds, wheezing, or crackles on listening to the lungs, are all indications that can help point towards a diagnosis. The next step is to order a radiograph or X-ray if pneumonia is suspected.

The radiograph still remains the reference standard for a medical diagnosis of pneumonia, and also helps to differentiate between bacterial and viral pneumonia. However, a combination of clinical symptoms, exam findings, and imaging is the best way to uncover the most likely culprit.3,4

Cover Your Mouth And Nose


While the preferred method for covering your mouth when you cough or sneeze is into a tissue, not everyone can get to tissues in time when the urge to cough or sneeze hits. If you have the urge to cough or sneezeand a tissue isnt availablethe next best thing is to cover your mouth or nose with the inside of your elbow.

Coughing or sneezing into your elbow will decrease the chances of your leaving traces of your infection on door handles, faucets, or anything else you touch.

Who Is At Risk For Pneumonia

Anyone can get pneumonia, but certain factors increase your risk for developing the illness. These include:

  • Being younger than two years of age
  • Being 65 years and older
  • Smoking
  • Having lung disease, such as asthma, chronic obstructive pulmonary disorder or cystic fibrosis
  • Having other certain health conditions or a weakened immune system due to diabetes, kidney disease, cancer treatment, human immunodeficiency virus or acquired immunodeficiency syndrome , an organ transplant or other factors

Bronchiolitis Obliterans Organizing Pneumonia

Bronchiolitis obliterans organizing pneumonia is caused by inflammation of the small airways of the lungs. It is also known as cryptogenic organizing pneumonitis .
Eosinophilic pneumonia
Eosinophilic pneumonia is invasion of the lung by eosinophils, a particular kind of white blood cell. Eosinophilic pneumonia often occurs in response to infection with a parasite or after exposure to certain types of environmental factors.

When Would I Need To Be Hospitalized For Pneumonia

If your case of pneumonia is more severe, you may need tostay in the hospital for treatment. Hospital treatments may include:

  • Oxygen
  • Fluids, antibiotics and other medicines given through an IV
  • Breathing treatments and exercises to help loosen mucus

People most likely to be hospitalized are those who are most frail and/or at increased risk, including:

  • Babies and young children
  • People with weakened immune systems
  • People with health conditions that affect the heart and lungs

It may take six to eight weeks to return to a normal level of functioning and well-being if youve been hospitalized with pneumonia.
